Abstract

Abstract

There is accumulation in the middle of the jets formed by the single cone liner in the annular shaped charge structure, and the length of the jet is limited before the fracture.The jet of the double cone liner takes both the high head speed formed by upper small angle cone liner and increscent effective mass of the jet formed by the lower cone liner.Therefore, the jet is more slender with high head speed and it is not easy to break.Based on the annular cutting shaped charge warhead, the influence of the upper cone size, the proportion of the upper cone cover, the mask height and the wall thickness of the liner on the penetration capability of jet is considered.It is concluded that the upper cone angle has the greatest influence on the jet molding.By comparison, when the top cone cover is 34°, the proportion of top cone is 40%, the height of the liner is 70 mm and the wall thickness of the liner is 5 mm, the jet head can fly steadily in the air with a high speed.Compared with the single cone liner structure, the jet formed by the double cone liner is long and slender, and has long flight time in the air, its penetration capability is greater than that of the single cone jet.
